I know ! She cannot be clueless and innocent in all this !!!!!
How could they live there knowing that they had a burned body buried in the backyard ????? How could they have hosted a BBQ practically on the grave ??? Wouldn't there be a terrible stench still ? ( Sorry so graphic ) How could they have preventing any guest from walking over to where the smell was coming from and pehaps asking questions about it ?
Wouldn't it have been so obvious to Xtina to see their fence all torn out and burned, her dog tied to the front yard instead of the back all of a sudden ? He probably didn't let their little daughter wander out in the backyard anymore, huh ? Xtina would have to have been in a coma not to see all the signs. I am so sure she had a hand in all of this.
Or perhaps maybe she was the one who actually killed Maria and now Cesar is the one taking the blame in order to spare their child of losing her mother.
I think maybe he told Maria he had to go home to pick up his atm card and Xtina walked in and caught Maria there. Or maybe she was already there waiting to ambush her. She could have easily struck Maria's head from behind repeatedly, thus resulting in the blunt object head trauma and the blood splatters on ceiling and walls. Then she and



disposed of Maria together, painted and cleaned walls, furniture, etc. , got rid of and burned rags and cleaning supplies, burned or threw away Maria's belongings and then proceeded to act as if nothing at all had happened. That is, until Sheriff Brown satarted sniffing around and called



in for questioning. At which time



lawyered up and refused to cooperate with the investigation. Then



and Xtina hatched the escape plan.
It was easier for him to eacape by himself and then they probably planned for Xtina and child to join him in Mexico later on after it all blew over. They never imagined it would go nationwide so fast. These are just some theories I'm trying out to see what fits.
